We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"Web filtering is a big improvement for us. The previous version we used, the AC520, did not have that feature included. It was not very easy for us, especially because the environment had to be isolated and we needed to get updates from outside, such as Windows patches. That feature has really helped us when we are going outside to pull those patches.""The solution offers very easy configurations.""The dashboard is the most important thing. It provides good visibility and makes management easy. Firepower also provides us with good application visibility and control.""You do not have to do everything through a command line which makes it a lot easier to apply rules.""Being able to determine our active users vs inactive users has led us to increased productivity through visibility. Also, if an issue was happening with our throughput, then we wouldn't know without research. Now, notifications are more proactively happening.""The most important features are the intrusion prevention engine and the application visibility and control. The Snort feature in Firepower is also valuable.""We get the Security Intelligence Feeds refreshed every hour from Talos, which from my understanding is that they're the largest intelligence Security Intelligence Group outside of the government.""One of the most valuable features of Firepower 7.0 is the "live log" type feature called Unified Event Viewer. That view has been really good in helping me get to data faster, decreasing the amount of time it takes to find information, and allowing me to fix problems faster. I've found that to be incredibly valuable because it's a lot easier to get to some points of data now."

"The interface and the dashboard are the most valuable features of this solution.""The graphic user interface is very good and it is user-friendly which makes the product easy-to-use.""I have found the solution has some great features overall, such as guest access capabilities, dashboards, and ease of use. There is plenty of documentation and support and it has the plugins that I needed.""We have found pretty much all the features of the solution to be valuable.""The solution is good for a basic firewall for a small business or for home use.""The initial implementation process is simple.""The VPN server feature is the most valuable. It is integrated with Radius and AAA for doing accounting and authentication. Insight view is also an important feature for me at this time. It allows me to assess our network traffic. I also like the firewall feature. The BSD kernel has a packet filter. It is one of the most solid frameworks for firewalls. Its user interface is one of the best interfaces I have used.""The most valuable features in OPNsense are reporting and visibility."

Cons
"Cisco Firepower NGFW Firewall can be more secure.""The initial setup could be simplified, as it can be complex for new users.""Web filtering needs improvement because sometimes the URL is miscategorized.""One of the few things that are brought up is that for the overall management, it would be great to have a cloud instance of that. And not only just a cloud instance, but one of the areas that we've looked at is using an HA type of cloud. To have the ability to have a device file within a cloud. If we had an issue with one, the other one would pick up automatically.""When you make any changes, irrespective of whether they are big or small, Firepower takes too much time. It is very time-consuming. Even for small changes, you have to wait for 60 seconds or maybe more, which is not good. Similarly, when you have many IPS rules and policies, it slows down, and there is an impact on its performance.""Cisco makes horrible UIs, so the interface is something that should be improved.""The price and SD-WAN capabilities are the areas that need improvement.""My team tells me that other solutions such as Fortinet and Palo Alto are easier to implement."

"The only thing that I would like to see improved is the Insight or the NetFlow analysis part. It would be good to have the possibility to dig down on the Insight platform. Right now, we can easily do only a few analyses. If this page becomes more powerful, it surely will be a well-adopted platform.""The solution would not be suitable for anything large-scale.""While they do have paid options that actually gives better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet.""The logging could improve in OPNsense.""There are issues with stability and reliability.""There should be more technical documentation.""I would like to see better SD-WAN performance.""The interface needs to be simplified. It is not user-friendly."

More OPNsense Cons »

"Although manageable, the user interface is a little bit slow and could be improved.""Sometimes it reboots when you least expect it, and that's the main issue."

Pricing and Cost Advice
"When we are fighting against other competitors for customers, whether it is a small or big business, we feel very comfortable with the price that Firepower has today.""This solution is expensive and other solutions, such as FortiGate, are cheaper.""The price for Firepower is more expensive than FortiGate. The licensing is very complex. We usually ask for help from Solutel because of its complexity. I have a Cisco account where I can download the VPN client, then connect. Instead, I create an issue with Solutel, then Solutel solves the case.""It definitely competes with the other vendors in the market.""When we purchased the firewall, we had to take the security license for IPS, malware protection, and VPN. If we are using high availability, we have to take a license for that. We also have to pay for hardware support and technical support. Its licensing is on a yearly basis.""I know that licensing for some of the advanced solutions, like Intrusion Prevention and Secure Malware Analytics, are nominal costs.""I am happy with the product in general, including the pricing.""The solution was chosen because of its price compared to other similar solutions."

"OPNsense is a well known open-source tool.""The solution is not expensive.""OPNsense is open source software so at this time it is free for us to use.""It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source.""OPNsense is an open-source solution and it is free to use.""As an appliance, it's in the medium price range."
